Google Maps has made speculative road trips easier than ever before. But when you actually make up your mind and decide to head out on one, wouldn't it be great if you could choose the route which had the best weather?

You type in your origin and destination, and it displays weather icons along the route so you can see what conditions are going to be like. Importantly, it takes into account journey time, too, so you don't see what the weather is like now along the route, but instead what the weather will be like when you arrive at every point. If there's rain, you can drag the route to change it and see how the weather changes before settling on the best option.
